GTA Online's Heist Patch is 4.8GB on Xbox One

Grand Theft Auto Online's upcoming Heist patch weighs in at 4.8GB on Xbox One, according to some lucky users who've managed to get it early.

Though the patch doesn't officially arrive until tomorrow, some users who've got it early report it's 4.8GB on Xbox One, while the Xbox 360 version comes in at a smaller 1.2GB. We don't know how big it is on PlayStation platforms yet.

Additionally, Xbox Achievements has managed to uncover nine new Achievements heading to the game for 250 extra Gamerscore. We don't want to spoil anything for you here, but suffice to say completing missions, beating a Heist without taking any damage and buying new cars are all part of it. There's even one for splitting the money earned equally, so you may want to search for a Gamerscore-hunting Heist leader!

Taking the fundamental concepts of open-world freedom, ambient activity and mission-based gameplay of the Grand Theft Auto series and making them available to multiple players in an incredibly dynamic online world, GTA Online offers the freedom to explore alone or work cooperatively with friends to complete missions.
